以澳大利亚大麦Gairdner和国产大麦垦啤7号为材料，在16℃、湿度为90%的条件下发芽，研究了制麦过程中麦芽β-葡聚糖含量和还原糖含量的动态变化。对定量测定麦芽的β-葡聚糖，采用了羧甲基纤维素钠代替标准大麦β-葡聚糖的方法，发现二者在550 nm处吸光值呈显著的线性相关，因此该方法方便可行且成本低廉。结果表明：在发芽的前期，麦芽的β-葡聚糖含量快速减少，同时还原糖含量也快速增加；发芽后期，麦芽β-葡聚糖含量下降趋于平缓，而还原糖的增加速度也趋于稳定。同时，在发芽过程中麦芽β-葡聚糖含量和还原糖含量还呈显著的负性相关性。

The Australian barley Gairdner and domestic Barley Kenpi NO.7 as material, germination at 16℃, humidity is 90 % ,studied during malting malt β-glucan content and reducing sugar content of the dynamic changes. The quantitative determination of maltβ-glucan,carboxymethyl cellulose sodium was adopted instead of the standard barleyβ-glucan and it was found that both in the absorbance at 550 nm was a significant linear correlation.The method was feasible and convenient low cost. The results showed that malt β-glucan content quickly reduced while the reducing sugar content increased rapidly in the early stages of the germination ,while in the late of germination, the maltβ-glucan content decreased to flatten and the increasing speed of the reducing sugar stabilized. Meanwhile, in the germination process of maltβ-glucan content and the reducing sugar content showed a significantly negative correlation.
